According to Shimano’s figures, the new Dura-Ace groupset weighs a total of 2,438g with the regular non-power meter chainset, compared with the 2,403g of R9100 (again non-power meter).
Meanwhile Ultegra R8100 weighs 2,716g compared to R8000’s 2,705g.
As for pricing, again it depends on the spec, but with the power meter groupset the list price of a complete Dura-Ace R9200 groupset will be around £4,350 by our calculations. Each individual component is a little more expensive than R9100 (£4,085 at Hargroves when we checked).
Ultegra we calculated to cost £3,099 with the power meter chainset, maintaining that £1,000-plus gap to Dura-Ace.
